SCHEDULE 55
POWER COST ADJUSTMENT
APPLICABILITY
This schedule is applicable to the electric energy delivered to all Idaho retail Customers served
under the Company s schedules, to the primary portion of the FMC Special Contract and to all other
Idaho retail Special Contracts. These loads are referred to as "firm" load for purposes of this schedule.
BASE POWER COST
The Base Power Cost of the Company s rates is computed by dividing the Company s power
cost components by firm kWh load. The power cost components are the sum of fuel expense and
purchased power expense (including purchases from cogeneration and small power producers), less
the sum of off-system surplus sales revenue and FMC secondary load revenue. The Base Power Cost is5238 cents per kWh.
PROJECTED POWER COST
The Projected Power Cost is the Company estimate, expressed in cents per kWh, of the power
cost components for the forecasted time period beginning April 1 each year and ending the following
March 31. The Projected Power Cost is 0.7971 cents per kWh.
TRUE-
The True-up is based upon the difference between the previous Projected Power Cost and the
power costs actually incurred. The True-up is 0.3583 cents per kWh.
POWER COST ADJUSTMENT
The Power Cost Adjustment is 90 percent of the difference between the Projected Power Cost
and the Base Power Cost plus the True-up.
The monthly Power Cost Adjustment applied to the Energy rate for Irrigation Service (Schedules
24 and 25) is 1.3163 cents per kWh, for Small General Service (Schedule 7) is 0.8481 cents per kWh and
Large Power Service (Schedule 19) is 0.8221 cents per kWh. The monthly Power Cost Adjustment
applied to the Energy rate of all other metered schedules and Special Contracts is 0.6043 cents per
kWh. The monthly Power Cost Adjustment applied to the per unit charges of the nonmetered schedules
is the monthly estimated usage times 0.6043 cents per kWh.
EXPIRATION
The Power Cost Adjustment included on this schedule will expire May 15, 2004.
